[jira] [Updated] (LUCENE-3803) Using a searcher with an executor service does not work from within a Callable called by that same executor service

Benson Margulies updated LUCENE-3803:
-------------------------------------
Description:
The test case I'm about to attach creates an executor service uses invokeAll to run things
from it. The 'things' (Callable) that it runs in turn run Lucene searchers using a searcher
that has the very same executor service. This turns out to hit some sort of deadlock related
to the executor service queue.
I won't be terribly surprised if this is really a matter of a fundamental limitation of the
executor service, but if nothing else this JIRA might provoke a warning in the javadoc. Or,
what do I know, maybe there's a way Lucene could interact with the executor service that gets
along with this?
